Intraocular silicone oil brain migration associated with severe subacute headaches: a case report

Abstract

Purpose: The aim of this article is to report a rare case in which a patient presented symptomatic silicon oil brain migration, documented by MRI, several years after vitreoretinal surgery. Methods: This is a case report with a prospective literature review. Patients: The patient described in the case report. Results: Case report. Discussion/conclusions: For several years, silicone oil (SiO) has been widely used as a long-term intravitreal tamponading agent to treat complex retinal detachments. There are rare reports in the literature demonstrating the migration of SiO into the brain. The aim of this article is to report a rare case in which the patient presented severe headaches several years after vitreoretinal surgery, with migrated SiO appearing in MRI as an oval lesion within the horn of the right lateral ventricle. To the best of our knowledge, there are very few reports of symptomatic SiO brain migration in the literature.
